SPECIFICATION forming part of Letters Patent No. 612,004, dated October4, 1898. Application filed December 16, 1895. Serial No. 572,290. d (Nomodel.)

T0 @ZZ whom it may concern,.-

Be it known that LWILLIAM J. KEEP, a citizen of the United States,residing at Detroit, county of lVayne, State of Michigan, have inventedacertain new and usefullmprovement in Stoves; and I declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it pertains to make anduse the same, reference being had to the accompanying drawings, whichform apart of this specification.

This invention relates to stoves, and has for its obj ect improvementsin base burning stoves whereby they are made with a less number ofpieces, and consequently a less number of joints, than heretofore andwhereby a stove can be disassembled and many ofV its heavy partsremoved, so that it can be much more easily transported and also so thatrepairs can be supplied and put in place in the stove-frame much moreeasily than heretofore.

Base-burning stoves are made with iiues at the back and the bottom,withside walls, and they are provided with an ash-pit within which isreceived 'an ashpan,which must be of considerable capacity. Above theash-pit is a fire-pot section, and above the re-pot section is acombustion-chamber partially occupied by a magazine,which lies stillabove the combustion-chamber. In front of the ash-pit is a door, whichshould be as Wide or nearly as wide as the entire ash-pit, andheretofore it has been customary to mount such doors on an independentframe which contained all of the hinges, catches, and seating-ledges. Infront of the lower mica doors there has been heretofore a part that laysubstantially level and formed the cover to the front of the ashpit, andupon the level part of the stove was comm only bolted an ornamentalnickel-plated hearth. The piece that supported the ornamental hearth hasbeen usually bolted to the door-frame for the lower mica doors.

My invention hereinafter described presents several features of noveltyand improvement over the features of base-burning stoves hereinbeforebriefly referred to; and it consists in making, first, a rigid base thatwill always retain its true shape, and upon this rigid base is erectedthe back of the stove, l

V`the interior of the stove.

The inner surfaces of the sides and the back are provided with ledges ortracks which are adapted to support the rings, one of which is called the grate-ring and the other of which is called the lire-pot ring. Theserings are diaphragms provided with suitable central openings andappurtenances to allow the grate or the fire-pot, as the case may be, tobe placed in position Within the ring and held there, while the ringitself is adapted to slide in or out along the side ledges of the stoveand is fashioned in its own contour to conform to the cross-section ofthe stove-frame at the lines where the ledges are located.

That side of each of the rings which comes to the front of the stove isprovided with suitable ledges or flanges, against which the mica doorsclose, and thus each ring becomes when in place a part of the door frameagainst which the door closes, the remainder of the door-frameconsisting of the front lower edge of the dome and the front verticaledges ot' the sides of the stove, which are provided with suitablehinges.

The sides of the stove just at the top of the ash-pit and the sides ofthe grate-ring which are adapted to engage therewith are provided withsuitable flanges, studs, and buttons, so that the hearths projectingfrom the gratering are seated closely against the parts of the stovesides and are held in place by suitable buttons.

The fire-pot ring is provided at the point where it engages the frontedges of the stove sides with suitable holes and lugs, so that bolts orbuttons canbe inserted through the stove sides and the lugs and theseparts can be drawn together and held in place.

On the hinge edge of each mica door is a wing which covers the hinge,concealing it from sight, and which swings with the door.

IOO

IVhen closed, the wing on the doors of the combustion chamber and thewing on the doors of the fire-pot chamber are in line and form acontinuous wing from the top to the bottom of those two chambers. Thisconstruction enables me to place the hinges for the doors on the cornerof the stove at the front edge of the stove sides, which could not bedone with the previous construction,where there was a framework for thedoors between the two sides and in front of the stove.

The grate -ring contains bearings for the trnnnions of the grate, and atthe rear, above the bearings for the trunnions, are openings throughwhich project (when the parts are assembled) lugs that extend forwardfrom the inside of the back of the stove, so that when the parts areassembled the trunnion cannot be lifted out of its bearing and yet whenthe entire ring bearing the grate is pulled forward, as may readily bedone, the grate can be quickly removed, if desired. The gratering isheld in place by buttons which are preferably made with a flatthumbpiece, so that they may be readily turned with thumb and finger,and to prevent the escape of the ring from position by the button beingaccidentally turned in place there is at each side a depending lug onthe false hearth that drops behind the button and prevents its beingaccidentally turned.

A stove may be made with or without bottom or back fines; also, withouta magazine and without a fire-pot ring. In other words, this inventionrelates to details of construction.

Fig. et showsa removable iire-pot-supportin g ring. Fig. 5 indicates the means bywhich a fire-pot-supporting ring is sustained. Fig. 6 indicates themeans by which the grate-supporting ring is sustained. Fig. 7 shows thefalse ornamental hearth. Fig. 8 shows an end of the false hearthreversed, so that the under side of it is seen. Fig. 9 is across-section of the hearth and false hearth, taken through the buttonll, and indicates the manner in which the button is prevented fromturning. Fig. 10 shows the bearings in which the rear ends of thegrate-journals rest and the lugs which prevent the j ournals fromrising.

A indicates the leg-base of the stove.

5 indicates the base or bottom part of the stove-body, containing thebottom cross-flues of a base-heating stove and above these fiu es thepartition which forms the floor of the ashpit. The ash-pit is inclosedon three sides by the side walls B B and the back wall, which is notseen in the drawings, and on the fourth side by a door 9 and by a hearth6. This hearth extends from the front of a grate-ring 3 and terminatesforward in a skirting which constitutes the upper-edge side of thedoorframe. The iire-pot cavity is inclosed on three sides by the sidewalls C C and the back and on the front side by the double mica doors et4. The combustion-chamber, above the repot and below the dome, isinclosed by the side walls D D and the back and in front is inclosed bydouble mica doors l 1i". The seetions B C D of the side walls may bemade separately or integral, as will be most convenient for manufacture.At the meeting line of the side B and the side C (if made separately, orat a corresponding place if each side is made in one piece) is a ledge7, which is employed as a track upon which the gratering rests when theparts of the stove are completely assembled or upon which it can slidewhenever the stove is being assembled or disassembled for any purpose.At the front of the sides B B there are seats properly fashioned andshaped to engage with the edges of the hearth and skirting and makeclose joints therewith. The particular shape and configuration of thesepieces is immaterial, and they might be varied indefinitely to suitvarious patterns of stoves. The horizontal cross-section at the lineswhere the grate-ring and the firepotsupporting rin g (hereinafter spokenof) engage with the stove-frame is substantially rectangular, and theside lines of the two rings and of the stove-sections at the lines wherethe rings engage the sides should be substantially straight. The frontand back or either of them may be curved,

ICO

according to the desire of the manufacturer.

The grate-ring 3 is a flat plate having a circular opening and suitablelugs for the support of the grate and with its sides straight andparallel. The back line conforms to the back wall, (or partition infront of the back flues,) and the front is provided with a hearth 6 andskirting S, which extends forward and downward and constitutes theinclosing wall over the top at the front part and partially over thefront of the ash-pit, and, in connection with the iianges on the frontedges of the sides B B, constitutes the seat for the door 9. Within theopening and on the lugs 3@ 3C 3 is supported the grate, made in eitherone piece or two pieces, as may be preferred. The skirting 8 is providedwith holes 3 3d, through which pass the journal or journals of thegrate. At the rear the ends of the journals rest in bearings 12 l2, andlugs 3C 3, projecting from the back of the stove, engage over the endsof the journals and prevent them from rising from their proper place. Inthat part of the flange on the side pieces B B with which the skirtingengages is a stud l0, that engages with a notch 10 in the edge of theskirting, and a button latch ll is adapted to hold the parts securelytogether. I prefer to sink these buttons in cavities 11, so that thereshall be no protruding knob. Around the front of the plate is anupturned flange against which the doors 1i 4 close, and over the entirehearth is a false hearth 13, which conforms in its general shape to theIIO hearth beneath it. At that part which lies immediately over thebutton 11 there are a number of lugs between which the head of thebutton is received, and these lugs prevent the button from turning solong as the false hearth is in place. A notch 6"L is provided in orderto permit the end of the grate-bar to project therethrough or to bereached by a wrench. The end 6c of the second journal is preferablycovered and concealed by the false hearth.

Each of the mica doors 4 4 4 4a is provided at that edge to whichthe-hinge-knuckles are attached with a wing 4b 4b, that projects outwardand backward, forming an ornamental iinish for the edge of the stove,and conceals the hinges from sight. Vhere there are two sets of doors,as in the drawings, this ornamental skirting is apparently continuousfrom the top of the upper door to the bottom of the lower door.

Above the grate -ring and at a suitable height for the support of thefire-pot there is on each side of the stove a ledge or track, (indicatedat Eig. 5 at 4g 4%) upon which ledge the ire-pot-supporting ring (shownin Fig. 4) is adapted to rest. This ring consists substantially of aplate 4, having a central opening Within which the ire-pot 4d issupported and provided at its front side with an upturned extendingledge 4e, which forms the bottom seat for the swinging doors 4a 4a. Theextremities of the ledge 4e .turn back parallel with the side of thering and are adapted to engage the side walls D D of the stove and aresecured in place by short stove-bolts which pass through the side Wallsand through the notches 4f4f. This supporting-ring, with the fire-potsupported by it, is .easily removable from the stove or easily placedback in place without disassembling any of the parts oil the stove, andso, also, the grate-ring and the` grate-support are easily removed orreplaced without disassembling any parts of the stove.

What I claim isl. In combination with a stove-body provided with ledgesadapted to sustain a ring and permit the ring to slide thereon, a ringadapted to support an interior part of said stove and to slide on saidledges, means adapted to secure the ring in place in the assembledstove, said ring being provided with a seating-ledge adapted to engagethe door whereby it becomes in the assembled stove a part of thestove-frame, substantially as described.

2. In a skeleton stove structure, the combination of back, base andsides, and adome, the said dome and sides being each provided withseating-pieces for flanges upon which the doors may seat without aninterposed door-frame, substantially as described.

3. In combination with a skeleton stovefraine provided with supports,and a gratering adapted to slide to place on said supports,buttonsadapted to hold the rin gin place, a false hearth adapted to rest oversaid buttons and provided with lugs adapted to engage the button-headsand prevent the buttons from turning, substantially as described.

4. A stove-frame having top, back, bottom and sides, but with its frontentirely open, hinge-knuckles for doors at the sides, removable ringsadapted to support the inner parts of the stove, and provided withseat-flanges against which the doors swinging from said knuckles areadapted to close, substantially as described.

In testimony whereof I sign this specification in the presence of twowitnesses.
